Bisset's beauty at 60 is the only fascinating thing in this mess of a thriller. Dad (Naughton) dies in a mysterious swimming accident, son (Garcia) thinks foul play, Mom remarries quickly, son sleeps with new stepsister (Evans). The plot twists and surprise revelations stretch things beyond the point of believability, the dialogue is terrible, and the performances lack any spark. It all adds up to a shallow, painful movie that will either induce groans or laughs.
